vMy invention relates to motor vehicles,

` and more specifically to an improvement 1n lill vehicle constructionparticularly Vuseful `in connection with small locomotives equipped`with internal combustion power plants.

Among the primary objects and advantages of the invention are first, abrake con- V tion` of a locomotive embodying one form.

Fig. 4 is a plan view of the power plant and transmission, including thecontrol mechanisms;

Fig. 5 is a plan view of the transmission proper, with parts broken awayto show tlm the change speed and reversing mechanisms;

Fig. 6 is a vertical central section substantially on line 6-6 of Fig.5;

Fig. 7 is a. transverse section on the irregular plane indicated by line7-7 of Fig.

,Fig 8 isa detail section on line 8V-8`of Fig. 6; Y i ig. 9 is anenlarged detail of one ofthe gear shift levers illustrated in Fig. 8;

Fig. 10 is a detail section on line 10-10 of Fig. 9; and

Fig. 11 is yan enlarged side elevation of tlhe brake, substantially on.line 11-11 of Power pla/nt.

The ower plant illustrated is an ordinary interna? inlet manifold 12 andexhaust manifold 14 discharging upwardly through stack 16. The radiator18 is preferably provided with a protecting grille 20.

To the rear of the crank case 22 is the usual clutch housing 24containing the manually controlled friction clutch used to disconnectthe motor from the transmission.

combustion engine 10, having the.

Back of clutch 24 is a cou ling 26 transmit# tIng power to the upperongitudinal shaft 28 in the gear shift casing 30.

Transmission.

The gears in casing 30 are arranged in the reverse of the customaryorder, the change speed gears being 'at the rear end of the casing, andthe power being delivered iinally from the front end. For locomotiveservice, no differential is necessary, and it is advisable to providefour different speeds in each direction. Accordin 1y, power may betransmitted from sha 28 -to the lower shaft 32 through any one of foursets of -spur gears. Shaft 28 carries gears 34 and 36 rotatable, butnon-slidableethereon, and a splined clutch 38 shiftable to clutch eitherof said gears to the shaft. lt also carries fixed gears 40 to 42 keyedon the shaft. Similarly, shaft 32 carries rotatable, but nonslidablegears 44 and 46 meshing with gears 40 and 42, respectively, and splinedclutch 48 for connecting either gear 44 or 46 to the shaft. It alsocarries fixed gears 50 and 52 meshing with gears 36 and 34, and keyed onshaft 32. It will be obvious that clutches 38 and 48 may be employed toconnect shaft 28 to shaft 32 at any one of four different speed ratios.Shaft 28 may be withdrawn forwardly through a suitable opening and shaft32 rearwardly through opening 39 (Fig. 6). 4Both shafts have bearingsclose to the gears in integral webs 41.

The front end of shaft 32 terminates rearwardly of the front end ofshaft 28, and carries a bevel pinion 54 constantly in mesh with each oftwo bevel gears 56 carried by sleeves 58, each supported by double ballbearings 460. Power delivery is through transverse shaft 62 to jackshaft 64 by means of spur gears 66 and 68, the connection between eitherbevelgear 56 and shaft 62 being established by splinedv clutch 70controlled by yoke 72 on shaft 74.

Referrin to Figs. 3 'and 6, it will be noted that jack's aft 64 islocated below and in front of transverse shaft 62 substantially midwayofthe combined length of the power plant and transmission above it. rlhejack shaft carries a keyed sleeve 76 having double sprockets 78 formedlthereon, from which drive chains 80 run to the axles 82. -It willtransi-'e'rse li'nlr 170 extends in to connect wit-harm 172 (see Fig.6), on shaft 74 for aci uating yoke 72.

Suitable connections for the throttle and spark timing o f the powerplant are provided. I have illustrated .throttlecontrol lever 174(see-Figs. 3 and 4), from which rod 176 runs directly to the throttlelever 178. Beside the throttle control is -the spark`control lever 180operating through longitudinal rod 182, bell crank lever 184, transverselink 186 and arm 188 to rotate rod 190 and control the adjustment of thetimer 192.

The. clutch control, and the brake lever are'not 'carried by thesub-frame; the for mer because convenience of the operator requires itto be positioned a'considerable distance to the rear of the end of thesubframe, andthe latter part-ly for thesame reason and partly because noprecise adjustment of the actuating means for rod 110 with respect tot-he rest of the mechanism carried by the sub-frame is ever required.'lhus the sub-frame carries a depending bracket 194 guiding the frontend of a rotating shaft 196 journaled at its rear end at 198 on the mainframe, and carrying the clutch foot pedal 200. Arm 202 on shaft 196actuates link 204, bell crank lever 206 carried by the sub-frame, link208 and the clutch control arm 210. .Brake lever 212 is pivoted at 214on the vmain frame, and carries a spring pressed'pawl 216 riding over aratchet sector 218, carried by the subframe. Rod 110 is connecteddirectly to lever 212. In separating the sub-frame from the main frame,it is only necessary to disconnect chains 80, rod 110, slip arm 202 oli'shaft 196, and slide the shaft rearwardly out of bracket 194.

lVithout further elaboration, the foregoing will so full)7 explain thegist of 'my invention, that others may, by applying current knowledge,readily adapt the same for use under varying conditions of service,without eliminating certain features which may properly be said toconstitute the essential items of novelty involved, lwhich items areintended to be defined and secured to me by the following claims.
